Abstract

<P>PROBLEM TO BE SOLVED: To provide an eaves structure of a building capable of suppressing an increase in cost and enhancing a construction efficiency. <P>SOLUTION: A case lateral groove 41A of the generally same as the outer wall lateral groove 22A of an outer wall panel 22 is formed in a shutter case 41. Therefore, since the design of the shutter case 41 is uniformed, the shutter case is not conspicuous even when viewed from the outside, and the aesthetic appearance is improved. Also, since the shutter case 41 does not need to be concealed by an eaves soffit member, a fascia board member and a lifting member for supporting the eaves soffit member do not need to be installed. Consequently, an increase in the cost of the parts can be suppressed, the assembly can be facilitated, and the working efficiency can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an eaves structure of a building having an inclined roof.

  In a building in which an inclined roof projects from the outer wall, a shutter case that houses a shutter provided on the outer wall may be disposed above the outer wall and below the eaves. In a building built on a narrow site, since the eaves protrusion dimension is shortened, there is a conventional example of an eave structure that corresponds to the case where the eave protrusion dimension is short (for example, see Patent Document 1).

In Patent Document 1, in a building having an outer wall and a roof panel, a shutter case is disposed above the outer wall, and an eave roof material is disposed from the parting material attached to the tip of the roof panel to the outer wall. It is shown. In order to conceal the shutter case, the eave ceiling material is supported by a nose concealment material or a suspension material attached to the roof panel, and is shown below the shutter case.
Japanese Patent Laid-Open No. 07-180308

  However, in patent document 1, since the length dimension of a roof panel becomes short according to a site, you have to adjust the height dimension of an eaves ceiling material with the length dimension of a roof panel. For this reason, nasal cover materials and suspension materials having various lengths corresponding to the height of the eaves are required. For this reason, a number of parts increases, cost becomes high, and workability falls.

  An object of this invention is to provide the eaves structure of the building which suppressed the increase in cost and the workability improved.

  Referring to the drawings, the eaves structure of the building of the present invention includes an outer wall member 22 provided with a window 23, a shutter case 41 disposed above the window of the outer wall member, and the shutter case covered with an eaves part. It is a building eaves-end structure provided with a roof member 31 that forms an inclined roof, wherein the shutter case has a pattern portion on which a pattern substantially the same as the surface of the outer wall material is formed.

  According to the present invention, since the shutter case is formed in a pattern substantially the same as the surface of the outer wall material, the design can be unified and the shutter case is not conspicuous even when viewed from the outside, and the design can be improved. Further, since it is not necessary to hide the shutter case with the eaves top material, there is no need to provide a nose cover member or a suspension material that supports the eaves top material. Therefore, an increase in component costs can be suppressed, assembly can be facilitated, and workability can be improved. Further, since it is not necessary to make the shutter case itself small in order to prevent the exposure of the shutter case, the shutter case can be used in common, and the increase in the parts cost can be further suppressed.

Here, in this invention concerning the eaves-end structure of a building, the structure in which the said pattern part is provided in the front and side surface of the said shutter case is preferable.
In the invention of this configuration, the appearance can be improved even when the pattern portion of the shutter case is viewed from an oblique direction.

The outer wall material and the pattern of the pattern portion preferably have a plurality of lateral grooves 22A and 41A extending continuously in the horizontal direction.
In the invention of this configuration, when the shutter case is viewed obliquely, a plurality of lateral grooves are continuously formed in the outer wall material and the pattern portion, so that design uniformity can be improved. Further, since the outer wall material and the pattern of the pattern portion are formed from the grooves, it is not necessary to provide a new member for forming the pattern, so that it is possible to suppress an increase in component costs.

The outer wall material and the pattern of the pattern portion preferably have a configuration in which vertical grooves 22B and 41B that are continuous in the vertical direction are formed.
In the invention of this configuration, not only the horizontal grooves but also the vertical grooves are formed, so that the design uniformity can be further improved.

It is preferable that the eaves top member 36 is provided to extend from the eaves of the roof member to the shutter case, and the lateral groove of the pattern portion is engaged and fixed to the end of the eaves top member.
In the invention of this configuration, it is possible to prevent insects and the like from entering the inside of the roof panel by providing the eaves top material. Further, the lateral groove formed in the pattern portion can be shared both when improving the appearance and when fixing the eaves top material. In other words, there is no need to provide a new member having a common pattern on the shutter case and the outer wall panel, and there is no need to provide a new member for fixing the eave roof material, so the number of parts does not increase. The workability and workability are improved and the cost can be greatly reduced.
